2 number word problem calculator

For 2011, I'm going to try to build some common word problems as well besides the mortgage calculator. Any ideas would be great. I just finished a 2 number word problem calculator that handles word problems that follow the following question format:

* Two numbers have a sum of 70 and a product of 1189 What are the numbers?
* Two numbers have a sum of 70. Their difference 32
* Two integers have a sum of 437 and a difference of 313, what are they?

These require real number solutions. I will try and expand on this in the future. Let me know if you want fixes or enhancements.

One of them results in a straight math calculation, while the other links to our quadratic calculator.

I created that over a year ago to demonstrate mortgage math for some friends and colleagues who were more than curious about their car/house payment and the actual math behind it.

I created the shortcut a few weeks ago so that people could click and go straight from the search engine if they had a word problem or a question.

For folks who are in Finance Math, I think it is a good intro lesson to basic annuities and present values. I added the amortization table and principal/interest early last year as well to show how much principal/interest/payoff one has left.

I grew up with Kellison's Theory of Interest book which was really helpful, and I crafted most of the Finance page straight from that book.
